Description: 1． 掌握压控振荡器的基本原理和调试方法。
二． 实验原理
压控振荡器，顾名思义，其输出频率随输入电压的改变而变化。它大致可分为两类，一类是调谐式，另一类是多谐式。多谐式一般线性好，但输出不是正弦波，只能通过间接方式获得。振荡频率一般较低。调谐式多用于发射机中，一般高频电子线性课程会有介绍。
这里介绍两种压控振荡器及其常用电路类型，供大家参考
-1. VCO master the basic principles and debugging methods. 2. VCO experimental principle, as the name implies, the output frequency with the input voltage changes and changes. It can be broadly divided into two categories : one is tuning, and the other is more harmonic. More generally linear harmonic good, but not sine wave output, and only through indirect manner. The generally low frequency oscillation. Multi-tuner for transmitters, the general linear high-frequency electronic curriculum will be introduced. Here introduces two voltage-controlled oscillator circuit and the type commonly used for reference

Description: 锁相回路可视为一个输出相位和输入相位的回授系统用以同步输入参考讯号和回授后输出信号。并让其操作同样的频率。如(图一)所示，简单锁相回路[3,4]是由三个电路构成，分别为相位侦测器（Phase Detector）、回路滤波器（Loop Filter）、压控荡器（VCO）-phase-locked loop can be regarded as a phase output and input phase feedback system for synchronous reference input and feedback signals After the output signal. And allowed to operate the same frequency. If (Figure 1), the simple lock-loop [3,4] by the three circuit. for the detection phase (Phase Detector), loop filter (Loop Filter), VCO finishes (VCO)

Description: 阻抗匹配与史密斯（Smith）圆图
在处理RF系统的实际应用问题时，总会遇到一些非常困难的工作，对各部分级联电路的不同阻抗进行匹配就是其中之一。一般情况下，需要进行匹配的电路包括天线与低噪声放大器（LNA）之间的匹配、功率放大器输出（RFOUT）与天线之间的匹配、LNA/VCO输出与混频器输入之间的匹配。匹配的目的是为了保证信号或能量有效地从“信号源”传送到“负载”。-Impedance matching and Smith (Smith) Smith chart in dealing with the practical application of RF system, there would always encounter some very difficult work on the part of the cascade of different impedance matching circuit is one of them. Under normal circumstances, the need for matching circuits, including antennas and low noise amplifier (LNA) matching between the power amplifier output (RFOUT) match between the antenna, LNA/VCO output and mixer input match between. The purpose of matching is to ensure the effective signal or energy from the " source" sent to the " load."
